Urban air pollution poses severe health and environmental risk, yet traditional air quality monitoring systems
are often expensive and limited in coverage. With the goal of offering a practical and affordable way to measure pollution levels in cities, this research investigates the application of IOT enabled sensors for air quality monitoring. With the use of a hybrid sensor network that consists of both stationary and mobile sensor nodes placed throughout cities, this study suggests an Internet of Things-based air quality monitoring system. This
study aims to give policymakers, urban planners, and the general public practical insights to reduce air pollution and enhance environmental and public health outcomes. The research’s main conclusions include improved coverage, high sensor sensitivity data correctness and calibration, etc. The methodology involves selecting IOT sensors for pollutants such as CO(Carbon Monoxide), NO2(Nitrogen Dioxide), and SO2(Sulphur Dioxide) and
integrating them with microcontrollers for data acquisition. In urban pollution hotspots, sensors are placed to provide real-time monitoring and easily navigable alerts. Lastly, policymakers are assisted in putting protective measures into place by impact assessments and suggestions. Urban air quality monitoring,
Smart City integration, industrial emission monitoring, etc. are examples of practical applications for this research concept. According to the study’s findings, an IoT-based air quality monitoring system offers real-time tracking of several pollutants, facilitating data-driven decision-making, dynamic adaption, and prompt alarms for better urban air quality management. In order to facilitate real-time data collection and analysis, this study introduces an Internet of Things (IoT)-based air quality monitoring system that combines inexpensive, multi-pollutant sensors (CO, NO, SO, PM2.5, PM10, and O) with wireless connectivity options like LoRAWAN, 5G, and cloud-based APIs. Furthermore, machine learning models and analytics driven by AI are used for early warning alerts, predictive insights, and automatic data calibration.
